Since starting my Win 10 Pro computer today, Thunderbird 115.4.2 (64-bit) has been "dead in the water". When it's launched, it posts the customary "Downloading Message 1 of [N]" status report, but then hangs right there, takes 3 or 4 minutes even to (re-)populate the tabs and panes that had been open, doesn't get past the alleged first new msg even in 15 or 20 minutes. When it does populate the Inbox pane, it shows no messages newer than last night just before shutdown. Very sluggish response to cursor, too: for ex. 30 seconds from clicking on a msg title in the Inbox pane to displaying that msg, even longer to bring up Help/About (with "Not Responding" shown in its title bar.)

  I get my mail through gmail's IMAP server but prefer to use Tbird's interface . Thinking there might be something evil about the first msg that was waiting to be downloaded, I used gmail's web interface to review everything new since last night, deleted several msgs that had attachments, then started Tbird again.  No change.  Can't even get Tbird into the "Work offline" state because it attempts download-of-new-msgs immediately after being started.
  The only consistently effective way I have found to STOP the hung Tbird is through (Classic) Task Manager's "Processes" list, which usually shows five or six "thunderbird.exe" instances.  After selecting whichever has the largest memory allocation I click on "End Process."
  This all "feels like" a bollixed internal state.  Does Tbird store internal-state information in its own file, or is it buried in the Registry?   If I attempt restoration from a backup, which files are needed; or is that unwise?
 I see there is a mid-April update available to 115.10; would installing it reset current messed-up internal state, or will that already messy situation prevent the update?   Is there any risk of losing my Inbox, Sent, etc contents?

Thanks!!!

First, I am supporting a family member, who has TB configured on two separate machines. Configuring for Comcast IMAP+SMTP, in the usual manner; nothing esoteric about that, all very routine.

Machine A seems to be working okay, no errors. TB up to date on this machine, connected over an ethernet wire, if that makes any difference.

Machine B, getting spam prompted over IMAP 1014 errors. No other information is provided than 1014.

I have tried dropping the account configuration hundred percent, restarting TB, re-adding the account configuration, to no avail. Still spam 1014 errors.

I did happen to notice TB needed an update, so I did that as well. Still 1014 errors.

I have also tried dropping that email saved password from the saved passwords, and responding to the subsequent re-enter password prompt. Also to no avail.

What if anything might have changed, and how can we contend with this? What is so corrupt, do we need to be mucking around in any AppData files, roaming files, etc?

We are not the only ones, apparently, to have bumped into this issue. Not sure if this is also Comcast specific, since a recent TB and/or IMAP specification change, i.e. maybe we try with a gmail account, for instance.

Wondering also, is it IMAP and/or Comcast somehow tieing Machine A to the IMAP and not releasing that association? Knowing a little bit about IMAP in this regard. And/or somehow now prohibiting Machine B+ from establishing a connection?

I've been reorganizing my folders, and while working on this, I will occasionally find that I can no longer create a new folder or rename an existing one, or, somewhat worse, when I rename a folder, it will disappear, along with the messages that were in it. The messages that were in the missing folder don't show up in a search, and aren't in trash.

If I close Tbird and quickfilters, and sometimes also restart the computer, the functions again work as they should (but the missing folders do not reappear). Rebuilding the parent folder doesn't recover the missing subfolder. The problem can happen when Tbird is the only open application.

Any idea what can cause this? Or where the missing emails might be?

Thanks Kent

Greetings: Here is an error message that is now so common that I can no longer send email to any account. Also, I have not been able to send email to any gmail account for last year or two. Please help. Error Message:

"Sending of the message failed. An error occurred while sending mail. The mail server responded: <MattMcKeegan_PLS@proton.me>... Relaying denied: You must check for new mail before sending mail.. Please check the message recipient "MattMcKeegan_PLS@proton.me" and try again."

Thanks. Matt.

there are often times when I go to websites, usually when I'm logging in or signing up for an account, where they have a pop-up window for me to enter in the information, which usually also includes a captcha, but for some reason I am unable to scroll up or down, and I'm unable to access a submit button as well, therefore unable to complete the process.

this is on my Kyocera e6920 AT&t version 6.103at with Android 10 and a updated version of Firefox.

I belong to almost a dozen regional 'yard sale' groups, and suddenly can no longer post 'for sale' in ANY of them including Marketplace. Yet in the same groups I can post and reply to messages

Created several email mailing lists. Stored them in the Personal Address Book (PAB). I'm sorry, but Thunderbird doesn't seem to work like any other email client. How do I address an email using one of those mailing lists in the PAB. Tried typing the whole name of the mailing list in the To: field. Didn't work. I'm not entirely stupid but it doesn't make sense to me.

Error message 'side by side configuration error'. I've been advised to re-install Thunderbird but not sure if I will lose my many thousands of emails and my address books etc.

A few months ago

If I deleted an email or moved it to another folder - on my apple app for any of the accounts that I also have on thunderbird

The changes would sync seamlessly - a few seconds after I deleted or moved an email on my apple iPhone mail app - on my laptop - thunderbird would show the same changes.

The same worked the other way if I deleted or moved an email on thunderbird on my laptop - my iPhone would show the changes in seconds.

However now if I do the same on my iPhone The changes do not show up at all.

BUT if I do the changes on my laptop - they will show on my iPhone. It just doesn’t work if I do the changes on my iPhone.

Is there a reason for this?

My wife is an ardent and long-time Thunderbird user. She has tens of thousands of old emails organized into dozens of folders. Recently she noted that many folders contained scrambled emails. For example, an email titled "The race to re-design sugar" from Sept. 2020 now contained what looked like content from an email from Office Depot. See below for a short piece of the body of the email. Anyway, I ran Thunderbird's "repair folder" function and not only did it not unscramble the emails, it also seems to have deleted any emails prior to 6 months ago. Fortunately I've got her T-Bird profile file backed up daily, so was able to restore the original (but scrambled) emails. Any thoughts? I use outlook, but I've got pretty good PC skills if you need to take me into the weeds. Thanks!

Example of one of the scrambled emails: 'From - Sun Feb 4 12:28:28 2024 X-Account-Key: account5 X-UIDL: AEZHkUhl+QCXZb/zNgpcWOY28vQ X-Mozilla-Status: 0009 X-Mozilla-Status2: 00000000 X-Mozilla-Keys: Received: from 127.0.0.1 by atlas-sbc-production.v2-mail-prod1-bf1.omega.yahoo.com pod-id atlas--sbc-production-bf1-7448fd4479-zt82t.bf1.yahoo.com with HTTP; Sun, 4 Feb 2024 20:27:34 +0000 Return-Path: <error@em.officedepot.com> X-Originating-Ip: [20.57.66.208] Received-SPF: pass (domain of em.officedepot.com designates 20.57.66.208 as permitted sender) Authentication-Results: atlas-sbc-production.v2-mail-prod1-bf1.omega.yahoo.com; dkim=pass header.i=@em.officedepot.com header.s=officedepot; spf=pass smtp.mailfrom=em.officedepot.com; dmarc=pass(p=NONE) header.from=em.officedepot.com; X-Apparently-To: xxxx.xxxx@att.net; Sun, 4 Feb 2024 20:27:34 +0000 X-YMailISG: T.w7qP0WLDtIndBfVsii11yVLG9YUwuh8bXrpNWGHf2Ezt9n W35tfL8ReGJq0phUGg1KeSNel41YbOoogg21rDC6q0i7xvo0jIbdikP0kWCS '

Once again Firefox has decided to take over and change all my settings! I had finally managed to prevent it updating, as each and every time I had to reinstall all my setting and extentions from scratch. Today, it decided to clear all my preferences and change itself to its own default settings. OK, so I can change my profile option, except all three are using the same defaults: I appear to have lost all my settings and extensions entirely. OK, I'll copy from my backup, but once again the three backup profiles are being overwritten with the defaults. Even my third backup of last March overwrites to the defaults! How and why is Firefox managing to keep overwriting my defaults to its own preferred settings? How do I stop it doing this and regain my own preferences?

I also tried Sync and now I am getting bookmarks from over five years ago! And once again my settings are changing to the defaults. Surely a Sync should overwrite with the current bookmarks and settings not just keep adding more and more. I am now in a right mess again. Back to losing everything with updates. I am a great believer in the 'if it ain't broke don't fix it' mentality, but Firefox has broken itself and is refusing to allow me to change to how it used to be! How do I restore my own preferences and prevent Firefox from changing them to what it wants.

Suddenly I can't sign-in to Sharepoint or Sharepoint admin console using my normal Firefox window. It works with the private window, but not the normal one. I've tested on another computer with the same firefox account sign-in and synced and it lets me sign-in there no problem. I've tried "Refreshing" Firefox, and that didn't work. I've tried uninstalling Firefox, deleting all the folders in appdata, then re-installing. Then I tried again before signing in to my Firefox account or syncing anything and it still didn't work. Any other suggestions? All the other O365 cloud login sites work, just not Sharepoint for some reason! It'll ask for my login credentials, then try and load, and then ask for my credentials again, over and over. Windows 10 Enterprise, Version 10.0.19043 Build 19043. Firefox 126.0 (x64).

Received an encrypted message but the content appears to be only my public key. Message not visible. Copy of same message was displayed in the clear in gmail on a computer that not set up to encrypt. Any suggestions gratefully received.
